<p>Hi,</p>
<p>I currently have this book: AP</a> U.S. History Crash Course (REA: The Test Prep AP Teachers Recommend): Larry Krieger, Advanced Placement, US History Study Guides: 9780738608136: Amazon.com: Books</p>
<p>Is this the REA book that everyone recommends? It seems pretty short but covers quite a bit of material.</p>
<p>As for AMSCO, would I be able to finish it in time for the AP test (I will be late testing due to a scheduling conflict)? Is it helpful to just read it once?</p>
